“…In general, digital electronic devices that make extensive use of high-speed, low-power integrated circuits are less resistant to electrostatic discharge (ESD). Therefore, an increase in human body potential often causes the destruction of digital electronic devices [ 1 , 2 , 3 , 4 , 5 , 6 ]. An increase in the potential of the human body is often caused by frictional charging, owing to daily motion, such as a walking motion.…”

This paper describes a non-contact and real-time measurement technique of human body potential using ultra-sensitive electrostatic induction. When a participant moves his/her palm to a position approximately 30 cm away from an electrostatic induction sensor, electrostatic induction current flows transiently. It is clarified whether estimation of the human body potential is possible by simultaneously measuring the velocity of the participant’s palm and distance between the participant’s palm and sensor. In addition, even when the participant walks at a position approximately 50 cm away from the electrostatic induction sensor, it is confirmed that the estimation of human body potential is possible.

“…Static electricity is used for electronic equipment in the field of industrial electronics for such devices as laser printers, but static electricity causes equipment malfunction and failure [1][2][3][4][5][6][7][8][9][10]. Such a problem of electrical safety cannot be ignored with the decrease of the operational voltage and breakdown voltage of an electronic device.…”

Electrical equipment within a metal box may malfunction by an electrostatically induced voltage. The induced voltage of the metal box is changed by the movement of a charged body, such as a charged human body. The induced voltage of the metal box generated by the approach and isolation of the charged body is experimentally studied in this work. In the experiments, the depth of a metal box is changed, and the result shows that the induced voltage of the metal box generated by the isolation of the charged body is higher than that generated by the approach of the body. The former induced voltage of the metal box becomes the voltage of approximately -400% of a latter induced voltage in this experimental condition. Electric charges of metal boxes are somewhat dependent of the depth of the boxes. These results will be useful to design electrical equipment capable of preventing equipment malfunction and failure.Keywords-electrical safety; electrostatically induced voltage; malfunction and failure; depth of metal box; moving charged body

A human body is occasionally electrified in a room. This charged object will be a source of electrostatic accidents, including the malfunction of electronic equipment. Hence, prevention of these accidents is required. Accidents occasionally occur, even though antistatic clothes and shoes are used. One of the causes for these accidents is that there is a lack of the preventive measures. This situation occurs when using, for example, unconductive wax. In this study, human body potential (voltage) is measured using a non-contact measuring system. An investigation of the human body’s voltage when using this system is conducted. The result demonstrates that the voltage of a human body wearing antistatic clothes and shoes or light clothes and slippers exceeds a malfunctioning voltage of a microelectronics device when the body walks on floors. Thus, accidents may occur even if a human body wearing the antistatic clothes walks on flooring. These results will be useful in estimating determination whether electrostatic accidents occur or not.
